RESUME / PORTFOLIO FRAMING
Describe what you actually did.
Designed an event-driven order service with idempotent processing, retries and observable failure handling.
Use this as a starting structure, then replace it with your real implementation details, metrics and constraints. Do not claim outcomes you did not measure.
STRETCH GOALS
Go deeper if the core is already solid.
Outbox pattern
Add only if it strengthens the engineering story instead of delaying a finished, deployable core.
Saga workflow
Add only if it strengthens the engineering story instead of delaying a finished, deployable core.
Replay tooling
Add only if it strengthens the engineering story instead of delaying a finished, deployable core.
